concealment writes: "In some cases, Microsoft will take calls from outside outfits interested in licensing its patents. RIM or Apple, say, will phone and ask to license Microsoft’s ActiveSync technology, a means of synchronizing email, contacts, and calendar entries across phones and other devices. “That’s a pretty friendly set of discussions,” Kaefer says.

But as he puts it, Microsoft will also “pro-actively” drive licensing deals. “We will go out and look for areas where we see a lot people who are probably using our technology in one form or another,” he says, “and we kinda ask ourselves whether it has risen to a level that we care about and we want to have some conversations.” Basically, this involves a Microsoft lawyer like Kaefer trying to convince lawyers at other companies that their technology infringes on Microsoft patents — and that they should pay to license those patents. According to Kaefer, these discussions can spans months — or even years."Link to Original Source
